BBC South don't cover us for the simple reason that Brighton isn't in their region. East Sussex is covered by BBC South East, who do cover the Albion reasonably.
But I'm pretty sure most people in Brighton watch BBC South rather than South East so surely it is their region.
Apparently in Oxford they get half of South Today and then switch to BBC Oxford for the second half of the news, surely that is the way to go as it would include the sport.
